Definitions
- the invention relates to a device for cyclically cleaning the doors of coke ovens, comprising means for producing a cleaning jet dissolving from the furnace for deposits,
- coke oven doors are heavily soiled. These are primarily tar deposits, which can significantly affect the sealing of the oven chamber by the oven, therefore, in particular, to avoid emissions, the doors of coking ovens are cyclically cleaned;
- the invention has for its object to perform the cyclic cleaning of the doors of coking ovens at least the same efficiency environment-friendly than the prior art.
- the marketssfrahi has solid particles.
- solid particles prevent the formation of aerosols and thus the spread of particulate particles from the cleaning site into the environment.
- the obtainedsstrahi is formed exclusively by solid particles and, if necessary, moreover, comprises only a transport gas transporting the particles.
- the particles of makesstrohls dry ice and are in particular formed exclusively by dry ice. Due to the dry ice, there is occasional excessive cooling and embrittlement of the tar deposits, which favors the tar popping off during the impact of the solid dry ice particles. Therefore, cleaning of dry ice particles not only advantageously avoids aerosol formation and propagation, but also remarkably increases the cleaning efficiency.
- a particular advantage of cleaning with dry ice particles is also a gentle treatment of the door surface, inter alia as a result of rapid sublimation.
- the means for generating the cleaning jet further comprise means for varying parameters of the cleaning wire.
- the size and speed of the fixed jet particles and thus their impact energy can be changed.
- the temperature of the dry ice particles may also be considered as a variable parameter.
- said means are provided for varying the parameters for controlled or controlled variation.
- a parameter to be controlled in particular the position and / or cross-sectional shape of the cleaning jet into consideration. Accordingly, the watersssfrahi is automatically guided over the preferably arranged separately from the coking oven in a cleaning position door. It is understood that a cleaning straw: generating nozzle could also be moved by hand,
- the means for controlled variation of the parameters may comprise a sensor detecting the degree of cleaning achieved, e.g.
- the guidance as well as changes of the cleaning jet then depend on the detected cleaning effect, whereby, if necessary, in order to accelerate the cleaning effect, the particle flow rate, the particle velocity and / or the particle size can be changed.
- a possible change in the cross-sectional shape of the cleaning jet may be, for example, a fan-like upgrade.
- Fig. 1 shows a device according to the invention in a schematic representation
- Fig. 2 is a ralif laugh of a cleaning jet of the apparatus of Fig. 1 on a furnace to be cleaned
- a device for the cyclic cleaning of the doors of coke ovens shown schematically in Fig. 1 comprises a support means 1 for receiving a furnace door 2 dismounted for cleaning by a coking oven (not shown).
- the elongated oven for 2 is! in the embodiment shown! horizontally on the support device 1, wherein the side facing the furnace interior side of the door 2 facing upward.
- a structural unit 3 which generates a cleaning jet 4 which is directed towards the door 2 and exits from a nozzle 5 obliquely to the surface of the door according to FIG.
- the assembly 3 is according to arrow 6 and perpendicular to the arrow direction by a moving device 7 parallel to the door surface movable.
- An optical sensor 3 connected to the assembly 3 visually acquires the impact surface 10 of the cleaning jet 4 visible in FIG. 2 on the surface of the furnace for FIG.
- the cleaning section 4 produced by the unit 3 has solid particles.
- solid particles In the example shown are exclusively dry ice particles which are transported by a transport gas. Means for producing suchnic toneistrahis are commercially available and need not be described in detail here.
- a programmable control device 9 controls the position of the cleaning jet 4, in particular the position of the impact surface 10 on the door 2, via the movement device 7 connected to the structural unit 3.
- the control device 8 also acts on the structural part 3 generating the cleaning jet 4 in order to move the cleaning device 4 Change cross-section of the cancellation grid. As shown in Fig. 2 shows let the cleaning! vary in width by more or less fanning.
- the adjustment of PosHion and Quefitessform the Resnistsstrahis 4 is controlled by the signals of the optical sensor 8, from which the
- Control device 9 determined by image evaluation the degree of cleaning achieved.
- the cleaning intensity can be varied with a constant position of the assembly 3, a'ass the wrongsstraht 4 is fanned more or less far, which depends on the degree of contamination only when reaching a predetermined degree of cleaning a further advance of the cleaning beam. 4 or its AufpralSfiamba can be done.
